Cuisine & Edibility
Arapaima
Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.
Brook Trout
Delicate, sweet flesh with a nutty, mild flavor; low fat and fine texture. One of the most prized freshwater eating fish in North America — best pan-fried simply in butter with herbs.
Species Overview
Arapaima
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
Brook Trout
The brook trout is actually a char, native to cold, clean streams of eastern North America. Its olive-green body with distinctive worm-like markings (vermiculations) and red spots with blue halos make it one of the most beautiful freshwater fish.
